A set of data consists of the following 6 numbers

A set of data consists of the following 6 numbers: 0, 2, 4, 6,10 and 8. Which two numbers, if added to create a set of 7 numbers, will result in a new standard deviation that is close to the standard deviation for the original 5 numbers?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
